Brand new in the box never even opened. The best I can find on the web is they are selling for $899-1049.99, I am thinking $800 would be fair. If you have an offer and a reason let me hear it. I do not need this unit for what I was planning so my lose your gain. Below is a cut and past from Humminbirds wed site about the unit. PM me if interested. Thanks Bud

To caveat in this, you are correct. The small SI units are not very desireable. Used units go for around $400-$450 on BBC. I think you could maybe get $500 out of that unit, maybe $550 since it's brand new. That's at at the high end as I believe Humminbird discontinued the 798. Good luck!
